METHOD AND APPARATUS FOR GENERATING IPV6 UNIQUE LOCAL ADDRESS

摘要

A method and apparatus for generating an IPv6 unique local address (ULA) are provided. The method includes generating a 64-bit first value using unique information on a UPnP device used by a router; generating a modified 64-bit EUI-64 using unique information on an interface device used by the router; generating a 128-bit second value by concatenating the 64-bit first value and the modified EUI-64; generating a 160-bit third value by applying SHA-1 to the 128-bit second value; and generating a global ID by extracting 40 bits from the 160-bit third value. A global ID is generated using unique information on an UPnP device and an interface device and the IPv6 ULA is generated using the global ID, thereby generating the IPv6 ULA having uniqueness in an entire IPv6 address system without an NTP.
